Re: 159 1.9 JTDm Hesitation/Poor MPG cure?
Glad you're sorted out - I probably get about 33mpg average too, but I just put it down to mostly short journeys.
Mine 'stuttered' twice when I first got it, less than 500miles on the clock. Both times on almost exactly the same piece of road, when I was doing ~20 on a steady throttle, maybe 1500rpm. I tried to make it do it again, thinking I'd book it in to get looked at if it did, but it never has so I just put it down to newness. Maybe there's more to it.
